Thank you very much for your help. Too bad I can't get zerex in my area (i'm using Valvoline oil in that Kia - very happy with it) - I could get it thru amazon, but shipping costs are terrible. Think I'm gonna use FL22 to top it off, and in about year or two will drain the system and fill it with FL22 - have been searching this forum and I find this (along with Ford Supreme Green coolant - which is also unavalible) to be the most identical to Korean OEM (Kukdong Yeyen Crown A105? or A103, i don't remember corectly).
